Support and configuration requirements

Before you add
Hitachi Data Systems (HDS) storage to
ViPR, configure the storage as follows.

Supported versions

For supported versions, see the
EMC ViPR Support Matrix on the
EMC Community Network (community.emc.com).

Required information

HitachiHiCommand Device Manager (HiCommand) is required to use
HDS storage with
ViPR. You need to obtain the following information to configure and add the
HiCommand manager to
ViPR.

Hitachi required information

Setting

Value

A host or virtual machine for
HiCommand Device Manager setup

HiCommand Device Manager license

HiCommand Device Manager host address

HiCommand Device Manager user credentials

HiCommand Device Manager host port (default is 2001)

Configuration requirements

HiCommand Device Manager software must be installed and licensed.

Create a
HiCommand Device Manager user for ViPR to access the
HDS storage. This user must have administrator privileges to the storage system to perform all ViPR operations.

HiCommand Device Manager must discover all
Hitachi storage systems (that
ViPR will discover) before you can add them to
ViPR.

When you add the
HiCommand Device Manager as a
ViPR storage provider, all the storage systems that the storage provider manages will be added to
ViPR. If you do not want
ViPR to manage all the storage systems, before you add the
HiCommand Device Manager, configure the
HiCommand Device Manager to manage only the storage systems that will be added to
ViPR.

After you add the storage provider to
ViPR, you can deregister or delete storage systems that you will not use in
ViPR.

Deregister or delete the storage systems that
ViPR will not manage

When you add a storage provider to
ViPR you add all the storage systems managed by the provider to
ViPR. Once a storage system is added to
ViPR it is automatically discovered and registered. Registered storage systems are available for
ViPR to use and manage.

If you want
ViPR to manage only some of the storage systems discovered with the storage provider, you can deregister or delete the storage system from
ViPR.

Deregister or delete storage systems from
ViPR

In the Admin Mode, select
Physical Assets > Storage Systems.

Select the box in the storage system row.

Click
Deregister to keep the storage system in
ViPR, and make it unavailable to use as a
ViPR resource.

ViPR storage system configuration

You can perform optional configuration steps on the storage system resources after the storage system is discovered in
ViPR. The configuration steps are not available until the resources are discovered and registered in
ViPR.

Once the storage system is discovered you can configure the following resources:

Define the storage system resource allocation limit

By default, storage systems are configured with unlimited resources that
ViPR can use. You can set resource limits, which define the amount of storage in the storage system that is available for use by
ViPR.

Deregister storage pools

By default, all discovered storage pools are available for provisioning in
ViPR. To make storage pools unavailable to
ViPR for provisioning, deregister them.

If a storage pool becomes unavailable on the storage system, the storage pool remains in the list of available
ViPR storage pools. You must deregister the storage pool manually in
ViPR to ensure
ViPR does not use it as a resource when a service operation is executed.

Procedure

Select
Physical Assets > Storage Systems.

Locate the row for the storage system in which the pools reside.

In the
Edit row, click
Pools.

Check the row for each pool that you want to make unavailable to
ViPR for provisioning.

Set the storage pool utilization limits

Storage pool utilization limits enable you to define the maximum amount of storage that
ViPR can use from a storage pool, the maximum number of volumes that ViPR can provision from a storage group, and the maximum subscription percentage for thin pool provisioning.

Procedure

Select
Physical Assets > Storage Systems.

Locate the row for the storage system where the pools reside.

In the
Edit row, click
Pools.

Click the pool name.

Change the maximum utilization percentage.

The default is 75%.

For thin pool provisioning, set a maximum snapshot percentage.

The default is 300%.

Enter a numeric value for the volume limit available to
ViPR to provision from this storage pool.

By default, there is no limit on the amount of a storage pool that can be used by
ViPR.

The Resource Limit value is a count of the number of volumes allowed to be provisioned using the selected storage pool.

Network configuration requirements for storage

After you add the storage system to ViPR, add the corresponding SAN Switch from the ViPR
Physical Assets > Fabric Manager page.

When you add a SAN switch to ViPR, the Fibre Channel networks (Brocade Fabrics or Cisco VSANs), are automatically discovered and registered in ViPR. Additionally, through discovery of the SAN switch topology, ViPR discovers and registers the host initiators for hosts on the network, and identifies which storage systems are associated with the SAN switch.
